Another fine and tricky puzzle with an unusual shape made by Eric Fuller (in 2017) and designed by Tim Alkema Eric's original comments :I've had Wedged on my list of puzzles to make for some time now. A very interesting twist on the traditional "pack the burr pieces in this box", Wedged captures one undersized burr piece right in the middle of the action. A level 17.4.12 solution makes you pay attention at all times to avoid getting lost. Tricky and beautiful, this is a must have for the burr p...

Nice little wooden lock designed by Robert Yarger and made by Eric Fuller in 2017.Eric's original comments :Robert and I have talked about reproducing some of his older work for a while. He sent me a few designs and this lock really grabbed me. Originally a component on his Pirate's Wallet puzzle box, he had many requests for the lock alone. It requires seven steps to solve and has a couple very tricky components. Note that this is a take apart puzzle, and the lock is not suited to actually secu...

Very unusual puzzle shape with very unusual puzzle pieces !Made by Eric Fuller in 2016. His original comments :RAR! How could I not make a puzzle named after dinosaur sounds?! Seriously though, this is one of the most unique designs I've seen in a long while, and I predict it will sell out very quickly. An unusual seven pieces forms a very unusual L shaped burr with a unique level 9.15.1.6 solution. The mechanics are odd and surprising...overall this is a super fun puzzle that will add a unique ...

The idea for the Escalating Box came from a couple of different mechanisms I'd been fooling around with. I was going to release them as two fairly simple separate boxes but realized that I could put them both into one trickier box. I made a poll on our Facebook Group and everyone overwhelmingly voted for a single, more difficult box. Done and done!I got to the drawing board and realized not only could I put both mechanisms together, but that they would interact making the sum more difficult than...

Small Box One - "Window Box" is a devious drawer tucked into a box with lots going on for its size. The large hole in the box serves as a window into the mechanism...careful observation and experimenting is necessary to reveal its secrets. I'm very happy with how this box turned out, the mechanism works flawlessly and repeatably once you know the scoop.The construction of this puzzle is sturdy and detailed. The mechanism depends upon extremely close tolerances which I'm happy to say we hit dead ...

Geneva is the first new puzzle by William Hu in quite some time. Named after the clockwork mechanism that it's partially inspired by, the level 9.3.4 solution includes some very unique rotations and coordinate motions. During assembly, there's a fair amount of freedom, with a lot of dead ends to run into and circles to run around in. Geneva is a nice addition to any TIC collection.This puzzle is shipped assembled.For multiple items, combined shipping is available. Simply message me once you are ...

The excellent 4L puzzle is back by popular demand! This is one of my favorite puzzles. 4L was awarded an Honorable Mention at IPP 2015 and is FAR trickier than it looks. The goal is to pack the four L shaped pieces into a very simple box. There are two different types of L pieces (fat and thin) and several possible configurations. The solution is extremely creative and devious.For multiple items, combined shipping is available. Simply message me once you are finished bidding and I will send an i...

The "TV Puzzle" is a long-discontinued Pelikan release that was the subject of particular obsession on the Mechanical Puzzle Discord. I somehow got roped into making it; I'm still not sure how. Those guys are persuasive.TV Puzzle is an interesting hybrid packing and take-apart puzzle. My interpretation stayed true to Jakub's original design with a couple of changes - we fully lacquered and changed grain direction for all pieces to make the solution more difficult. The result is trickier than I e...

Confetti Box was designed to cap off 2019, a great year which saw us make more puzzle boxes than we ever have before. It's festive, it's surprising, it's abrupt! This box went through several prototypes and redesigns, and I'm quite happy with the final result. The operation is a new concept for me and I'm eager to see how much of a challenge it proves to be.This puzzle is shipped assembled.For multiple items, combined shipping is available.
